Conflicts represent an error that has occurred due to an update operation. Conflicts are generated for many reasons. For example, another client has updated the same property of an item.
Conflicts are determined by both the remote destination and the local DataService. A conflict detected by the DataService is considered a local conflict. A conflict detected by the remote destination is a remote conflict.
This interface is used when detecting local conflicts.
Local conflicts are determined by the ConflictDetector object.
To customize local conflict detection the ConflictDetector
can be extended and assigned to the DataService.conflictDetector
property.
